<p>CDAP 是一个集成的开源应用开发平台, 基于 Apache Hadoop® 生态为开发人员提供数据和应用抽象层,
以简化和加速应用开发, 广泛支持实时处理和批处理场景, 并在应用满足企业需求时发布至生产环境.</p>
<p>CDAP 是运行在 Hadoop 平台, 例如 CDH, HDP, 或者 MapR 发行版之上的一层软件.
CDAP 提供以下至关重要的基础能力:</p>
<ul class="simple">
<li>通过底层数据的逻辑表示对 Hadoop 环境中的数据进行抽象;</li>
<li>通过底层基础框架解耦实现应用可移植性;</li>
<li>提供服务和工具支持在开发环境快速创建应用;</li>
<li>在单一平台中集成 Hadoop 生态组件;</li>
<li>通过企业最佳实践为生产环境提供高度操作和控制能力.</li>
</ul>
<p>CDAP 为创建应用和访问核心 CDAP 服务提供了开发 API (应用编程接口).
CDAP 定义并实现了一个广泛的服务集合, 支持 Hadoop 基础架构上存在的应用和数据,
例如 HBase, HDFS, YARN, MapReduce, Hive, 和 Spark.</p>
<p>这些文档是 CDAP 的完整参考手册: 它们帮助你开始并搭建开发环境; 解释 CDAP 工作原理;
并教你开发和测试 CDAP 应用.</p>
<p>它包括 CDAP 编程 API 和客户端接口, 以及安装, 监视和测试 Hadoop 集群上全分布式 CDAP 的操作指南.
CDAP 的功能包括 <em>CDAP 数据流管道</em> 和 <em>元数据管理</em>.</p>
